To use these bookmarks, simply place them between the pages of your book to mark your spot. They're great for any Harry Potter fan's reading adventures. When handling the bookmarks, be gentle as they are made of metal and resin, which can be fragile. Avoid dropping them or applying too much pressure. To keep them in good condition, wipe them gently with a soft, dry cloth from time to time. Store the set in its black branded card box when not in use to protect it from dust and damage.
